Expand description

R-external (background R-matrix) parameters for a single spin group channel.

Parameterizes smooth R-matrix contribution from distant (unresolved) resonances. The background R-matrix is diagonal and real-valued, parameterized as a logarithmic polynomial in energy.

§Formula

R_ext(E) = R_con + R_lin·E + R_quad·E²
         + s_lin·(E_up − E_low)
         − (s_con + s_lin·E)·ln[(E_up − E) / (E − E_low)]

Fields§

§l: u32

Orbital angular momentum L of the spin group.

§j: f64

Total angular momentum J (signed, per SAMMY convention).

§e_low: f64

Lower energy bound (eV).

§e_up: f64

Upper energy bound (eV).

§r_con: f64

Constant term in R-matrix polynomial.

§r_lin: f64

Linear coefficient (eV⁻¹).

§s_con: f64

Constant logarithmic coefficient.

§s_lin: f64

Linear logarithmic coefficient (eV⁻¹).

§r_quad: f64

Quadratic coefficient (eV⁻²).

Implementations§

impl RExternalEntry

pub fn evaluate(&self, energy_ev: f64) -> f64

Evaluate R_ext(E) at the given energy.

The polynomial part (r_con + r_lin·E + r_quad·E²) applies at all energies. The logarithmic terms are only added when E is strictly inside (e_low, e_up).
